  • a coke oven operations of carbonizing coal introduced into the oven for a certain period of time and discharging the formed red-hot coke outside the coke oven by a coke extruding apparatus are repeated.
  • firebricks forming the oven wall surface are subjected to mechanical or thermal impacts upon the introduction of coal or gradually eroded by, for example, parts of the firebricks being peeled off along with the carbon grown on the wall surface.
  • the oven wall surface of the coke oven becomes irregular, causing clogging in the oven during the coke extrusion operation. Clogging in the oven not only reduces operational efficiency of the coke oven but also places heavy load on the oven body, and even shortens the life of the oven body.
  • level differences due to the irregularity formed on the oven wall surface often increase and therefore, the clogging in the oven becomes easier to occur upon the coke extrusion. Accordingly, it is very important for operating a coke oven to maintain smoothness of a wall surface in the coke oven.

  • the irregularity information on the oven wall is obtained by irradiating the spot-like laser light to one point of each oven wall brick and therefore, irregularity information is not able to be obtained for the entire surface of the oven wall.
  • the technique described in Patent Literature 2 because the irradiation angle of the slit-like laser light is shallow, it is impossible to increase the measurable range in a direction perpendicular to the oven wall surface, and further, the laser light and the self-emitting light relating to the irregularity information are obtained simultaneously by the single imaging device and there is a problem that it is difficult to adjust both the incident brightness level of the laser light and that of the self-emitting light so as to prevent halation.
  • Patent Literature 3 discloses an oven wall surface measuring apparatus wherein a light beam emitter and camera apparatus are housed in a heat insulated container, a mirror surface is arranged at the outside of the heat insulated container, and the image of the oven wall surface reflected at the mirror surface is captured by the camera apparatus.

  • the difference in thermal conduction for each brick and the surface state of the bricks can be determined from the self-emitting light image.
  • the life of the oven can be prolonged by strategically repairing the oven on the basis of the above information.
  • the image processing unit generates the self-emitting light image of the oven wall surface and the image of the irregular shape by sorting a one-dimensional self-emitting light line of one line in a vertical direction in an image region in which the self-emitting light is imaged and a one-dimensional irregular shape line obtained by calculating an irregular shape of one line in a vertical direction of an oven wall on a basis of a principle of triangulation from an image of the slit-like laser light in an image region in which the reflected light is imaged, with respect to an intra-oven position of the oven wall shape measuring apparatus 1 detected by the position detecting unit. Therefore, both the self-emitting light image and the irregular shape of the bricks of the oven wall can be obtained at the same time.
  • the oven wall shape measuring method includes a position detecting step of detecting an intra-oven position of the oven wall shape measuring apparatus 1 by a position detecting unit, an imaging step of separately imaging reflected light of slit-like laser light emitted to an oven wall surface and self-emitting light emitted from the oven wall surface in one image, by the oven wall shape measuring apparatus 1, a one-dimensional self-emitting light line extracting step of extracting a one-dimensional self-emitting light line of one line in a vertical direction in an image region in which the self-emitting light is imaged, by an image processing unit, an irregular shape calculating step of calculating a one-dimensional irregular shape line in a vertical direction of an oven wall on a basis of a principle of triangulation from an image of the slit-like laser light in an image region in which the reflected light is imaged, by the image processing unit, and an image generating step of generating a self-emitting light image of the oven wall
  • the deterioration state of the oven can be recognized in a complex manner. While the deterioration state of the irregularity can be determined from the irregular shape image, the difference in thermal conduction for each brick and the surface state of the bricks can be determined from the self-emitting light image. The life of the oven can be prolonged by strategically repairing the oven on the basis of the above information.
  • the image generating step includes generating the self-emitting light image of the oven wall surface and the image of the irregular shape by sorting the one-dimensional self-emitting light line extracted in the one-dimensional self-emitting light line extracting step and the one-dimensional irregular shape line extracted in the irregular shape calculating step with respect to an intra-oven position of the oven wall shape measuring apparatus 1 by the image processing unit. Therefore, both the self-emitting light image and the irregular shape of the bricks of the oven wall can be obtained at the same time.
